Professional Applications & Engineering Value
This 316 stainless steel hex head screw delivers exceptional performance in corrosive and high-stress environments where reliability is paramount. The 1/2"-13 UNC coarse thread configuration enables rapid installation in structural steel, heavy machinery, and marine applications while maintaining Class 2A thread fit precision. The partially threaded design concentrates clamping force precisely where needed, preventing joint loosening under vibration. With 70,000 PSI tensile strength and superior corrosion resistance, these industrial hex screws solve critical challenges in chemical processing, offshore operations, and infrastructure projects where fastener failure is not an option. The external hex drive provides positive torque transmission for high-tension applications.
Specification Summary & Compliance
Manufactured to exact ASME B18.2.1 standards with Class 2A thread fit tolerances ensuring precise dimensional consistency. The 1/2"-13 UNC coarse thread maintains proper engagement across mating components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees material safety and regulatory acceptance for global industrial applications.
